so don't ask me why i was looking, but the solutions to my second year calculus exam are finally online!

i finally understand that y equalled 2.

this is the best day of my life.

something finally came along to trounce your purchase of that $4 louis-vitton-rip-off bratz baseball cap, eh? ASTOUNDING. =D

(btw, i have a picture of you and i in zeller's, wearing those hats, that you MUST see.)

If you were to take a topological approach and construct the set {y,yy,yyy,...} you could find a compact and totally bounded subset, {x1,x2,x3,...}. In which there exists a subsequence {i1,i2,i3,...} such that xin -> y. If we can prove that the real line is Hausdorff, then by the property of 2^n -> infinity, we can show that if xin converges to any y, it would have to be 2. Proof: given any two distinct points in the real line, say a & b where a < b, we can always find a number c that lies between a & b (because the real line is dense) and thus our two open sets, (a-2,c) and (c,b+2) are disjoint non-empty sets containing a & b respectively. Therefore, the real line is Hausdorff.

QED.

The other approach was to differentiate with respect to x, but I'm not good at differentiation.
